The cogl-texture-2d-private.h header checks for the presence of EGL_KHR_image_base before declaring _cogl_egl_texture_2d_new_from_image. This define will only be available if the EGL headers are included so we should make sure that happens. This was resulting in a warning complaining that the function was not previously declared.
